DiffServ Traffic Statistics
To view the traffic statistics for port Gi1/2, VLAN 100, based on DSCP values, Dean does the following:
Step 1. Select Monitor > DiffServ > Traffic Stats. The DiffServ Traffic Statistics screen is displayed.
Step 2. From the Data Source-Profile pull-down list, select VLAN 100 QoSsearch (enabled earlier for
monitoring). The DiffServ Traffic Statistics screen for VLAN 100 QoS search is displayed.
Dean can instantly see that all traffic for VLAN 100 on this link is using one of three DSCP values as
expected. Notice that there is no “other DSCP” group because all DSCP values have a label and are
accounted for. Next, Dean will view which applications have traffic for the different DSCP values. (0 is the
default so that probably would not be interesting to look at.)
